Half a dozen blades in your razor: it sounds great in a marketing pamphlet, but in practice it leads to irritation, redness, and ingrown hairs. At the same time, fiddling with standard single blades by hand isn't exactly appealing, either. Enter the Single Edge injector blades – eight sturdy stubble-slicers packed into a custom-built cartridge. The simple mechanism lets you reload your Single Edge razor with a satisfying click, avoiding all contact between your fingers and the blade.
